7 Claims. (Cl. 15365) This invention relates to suction cleaners and more particularly to a multiple purpose suction tool for attachmerit to a suction cleaner hose.

According to the present invention a suction nozzle is provided with two peripheral rows of bristles in such a manner that a single row or a double row of bristles may be presented to the surface being cleaned.

For cleaning furniture and other upholstered objects or surfaces, short stiff bristles are necessary while for other dusting purposes, longer more flexible bristles are desirable.

According to the present invention both types of bristles are combined into a single multiple purpose tool.

The end of the nozzle proper is provided with an inner peripheral row of relatively short bristles whereby those bristles are relatively stiff. Telescoping over the exterior of the nozzle is a sleeve member carrying an outer peripheral row of relatively long bristles whereby those bristles are relatively more flexible than those of the inner row. By moving the outer telescoping sleeve upwardly the ends of the outer row of bristles may be brought into alignment with the ends of the inner row so that the two rows will support each other against flexure and the brush will be relatively stiff. In that position the brush is particularly useful in cleaning furniture or other upholstered objects or surfaces. For dusting other surfaces the outer telescoping sleeve or member is moved downwardly whereby only the outer row of bristles will be presented to the surface being cleaned. The outer row of bristles being longer than the inner row and in lowered position being unsupported by the inner row of bristles, Will be relatively more flexible.

The outer telescoping sleeve or member and the nozzle proper are made of thermoplastic material and there is a comparatively tight friction fit between them so that the outer member will remain in either position while in use.

Other objects and advantages of the present invention will become apparent as the description proceeds when taken in connection with the accompanying drawings in which:

Fig. 1 is a plan view of the nozzle of the present invention looking downward.

Fig. 2 is a sectional view of the nozzle of Fig. 1 taken in line 2-2 of Fig. 1 and showing the outer row of bristles in extended position and Fig. 3 is a view similar to Fig. 2 showing the ends of the inner and outer rows of bristles in alignment.

Referring to the drawings, the reference numeral generally represents the multi-purpose dusting tool of the present invention. The nozzle proper is shown at 11 and is attached to a fitting 12 by means of a rivet 13. The fitting 12 is adapted to be connected to the wand of a suction cleaner hose in any manner well known in the art. A second rivet 14 is provided for a purpose which will presently appear.

The nozzle 11 is enlarged at 15 and is formed with a peripheral groove 16 in which an inner peripheral row Unitfid tates Patent 0 2 of bristles 17 is suitably secured. The bristles 17 are relatively short and therefore relatively stifi.

Slidabl'y or telescopically mounted on the exterior of the nozzle 11 is a telescopingsleeve member 18 having an" enlargement 19 formed with a re-entrantopening 20 in which is positioned a peripherally extending brush back 21. The brush back. 21 is formed with a peripheral The spline 24, rivets 13 and 14 and. grooves 25 and 26: prevent relative rotation between the telescoping sleeve= member 18 and the nozzle 11 while permitting teleseop-- The nozzle 11 and telescoping sleeve member 18 are made of thermoplastic: material and have a frictional fit between them so that: the sleeve member 18 will remain in either its extendeda ing movement between them.

or retracted position.

A split ring 27 fits in a groove in the periphery of the: nozzle 11 in such a positio'nthat when the'upper end of' the sleeve member 18 is engaged with the ring 27 the lower end of the bristles 17 and 23 will be in alignment. The nozzle 10 is formed with an extension 28 for sup porting the bristles 17 and to thus render them stiffer.

It is to be noted that the bristles 17 and 23 extend at an angle to their face and are thus presented at an angle to the surface being cleaned which renders them more suitable for dusting purposes.

In the position shown in Fig. 2 the enlargement 15 telescopes into the opening in the ring 21 to form a rigid compact arrangement.

Operation When it is desired to use the multiple purpose tool 10 for general dusting purposes, the fitting 12 is attached to the wand of the suction cleaner hose and the sleeve member 18 moved to the position shown in Fig. 2, in which the ends of the outer row 23 of bristles will extend beyond the ends of the inner row 17 of bristles. In that position the bristles 23 will be free to flex readily and the tool will be particularly useful for general dusting purposes.

If it is desired to clean furniture or other upholstered objects or surfaces, the sleeve member 18 is moved to. the position shown in Fig. 3, in which the ends of b0th' rows of bristles are in alignment. In that position the. outer more flexible bristles 23 will be supported by the: shorter more stiffer bristles 17 and the ends of both rows; of bristles will be presentedto the surface being cleaned. In that position the multiple purpose tool 10 is particu larly effective in removing dirt and lint from depressions and corners of upholstered objects.

From the foregoing it can be seen that the present invention provides a simple, easy-to-operate, multi-purpose cleaning tool for use with a suction cleaner which is simple and inexpensive to manufacture.

While I have shown but a single embodiment of my invention it is to be understood that that embodiment is to.- be taken as illustrative only and not in a limiting sense. I do not wish to be limited to the particular structure shown and described but wish to include all equivalent variations thereof except as limited by the scope of the claims.

I claim:

1. A suction nozzle having an outer row of bristles; about its periphery and an inner peripheral row of bristles slidably mounted within the outer row of bristles in a direction lengthwise of the bristles of the outer row so that the inner row of bristles may be brought into contact with the surface being cleaned to present two peripheral rows of bristles for cleaning purposes or moved upwardly into the outer row of bristles so that only a single row of bristles is presented to the surface being cleaned the arrangement being such that the ends of the bristles of said inner and outer rows of bristles are in substantial lateral contact with each other when both rows are in contact with the surface being cleaned whereby each row of bristles supports the other against lateral flexure to form a relatively stifi bristle arrangement.

2. A multi-purpose suction tool for use with a suction cleaner comprising, a suction nozzle proper, an inner row of bristles extending about the periphery of said nozzle, a sleeve member adjustably telescopically mounted on the exterior of said nozzle, an outer row of bristles extending about the periphery of said sleeve member and arranged to telescope over said inner row of bristles the arrangement being such that the ends of the bristles of both rows may be brought into alignment and into substantial lateral contact with each other when said sleeve is moved to and held in its uppermost adjusted position whereby each row of bristles supports the other against lateral fiexure to form a relatively stifi bristle arrangement.

3. A suction tool according to claim 2 in which the bristles of said outer row are longer than those of said inner row wherebythe endsof the bristles of said outer row may be extended beyond the ends of the bristles of said inner row by adjusting said sleeve downwardly relative to said nozzle.

4. A suction tool according to claim 2 in which the bristles of both rows extend at an angle to the surface being cleaned when the tool is in use.

5. A suction tool according to claim 4 including means to prevent relative rotation between said nozzle and said sleeve.

6. A suction tool according to claim 2 in which said nozzle and sleeve are made of thermoplastic material and have a frictional sliding fit with each other.

7. A suction tool according to claim 2 in which said nozzle is provided with an extension extending downwardly into said inner row of bristles to support the latter against flexure.
